'Big Sam' reckons the current crop of Red Devils will go down in history as the greatest team Fergie ever assembled...
And so impressed was he by Sir Alex Ferguson's mob that he declared they would soon become known as the Scot's most formidable side.
Allardyce told The Sun, “For me, [this team] will be the best. You look at this United team and you see youth, vibrancy, talent and more players with all those qualities than he has ever had before.
“As well as that, he has the last hurrah of the Fergie fledglings, as they were called. They are still in amongst it, showing how it should be done.”
Indeed, the likes of Ryan Giggs, Paul Scholes and Gary Neville are still going strong, with the former two in particular remaining indispensable cogs in the United machine.
“Those three will not let the other players forget ‘This is Manchester United, this is how it is’,” Allardyce continued.
“They still have a massive influence on the way Manchester United should be and the way you should be when you play for them.”
The Red Devils' win over the Cottagers put them five points clear atop the Premier League table, and they will continue their Champions League defence next week when they take on Inter in the last 16.
And does Allardyce believe United are capable of rewriting history by retaining both their European and domestic titles?
“I believe they can do it, definitely. And if they do that Double again, you cannot argue against them being Sir Alex’s best,” the former Bolton Wanderers boss said.
“You can’t see past them for the league right now and they showed last season they are the strongest side in Europe. They have got better since.
“No one wins the league and Champions League in successive seasons but they can. That alone will make them the greatest team Sir Alex has ever had.”
